PURPOSE:To efficiently gasify coal with little catalyst, by gasifying the coal after the coal is immersed in liquid ammonia in which a specified transition metal compd. is dissolved. CONSTITUTION:Coal crushed to a particle size of 1-2mm. is immersed in liquid ammonia in which 1-100g of a compd. of a group VIII transition metal of the periodic table per kg of the coal is dissolved, in a wt. ratio of the coal to ammonia of 1:0.5-10. After the coal particle is impregnated with the metal compd. and liquid ammonia by contact at normal temp. to 132 deg.C for a determined time, ammonia is removed by reducing pressure. Then the coal is gasified at 1- 100atm. pressure and 500-900 deg.C for 15min-2hr.
